Los Angeles - Kim Kardashian West was reduced to tears when she had to babysit her sister's kids.
The 33-year-old star agreed to look after her older sibling Kourtney's two children, Mason, four, and Penelope, two, while also caring for her own 14-month-old daughter North - with husband Kanye West.
Kim admits she struggled to care for all three kids and was "crying" at the end of the day when she finally got them all in bed.
During an appearance on The Ellen DeGeneres Show she revealed: "I took care of my niece, nephew, and my daughter. To bath them - all three - feed them, get them in their pyjamas and down for bed, I was literally crying!"
Kim added: "It was so hard, three kids. I don't know how my mom did it with six."
Kim's emotional babysitting experience has made her think twice about her previous wish to have a large family.
